My Python Turtle Roller Coaster

rollercoasterIn this challenge we will use Python Turtle to draw the track of a roller coaster.

We have created three procedures for you to use when drawing the track. Each procedure takes two parameters as follows:

  • straightLine(distance, speed): To draw a straight line. The distance is given as a number of pixels (e.g. 100) and the speed as a number between 1 and 6 to represent when the roller coaster is going up hill (low speed) or down hill (high speed).
  • turnLeft(angle, radius): to draw a turn / arc of a specific angle in degrees (e.g. 180 for a u-turn), and a radius to represent how sharp the turn is. (Sharp turn = low radius e.g. 10).
  • turnRight(angle, radius): Same as above but to turn to the right.

Your Challenge


Complete the track of your own roller coaster by completing the code below, making good use of the 3 procedures straightLine(distance, speed), turnLeft(angle, radius) and turnRight(angle, radius).
